CASH REGISTER Filed Oct. 22, 1938 6 Sheets-Sheet 6 Julia Patzelt Inventor By ghe/ M His Attorney Patented Oct. 21, 1941 CASH REGISTER Julius Patzelt, BerlimGermany, assignor to The- National Cash Register Company, Dayton, Ohio, a corporation of Maryland Application October 22', 1938, Serial No. 236,507 In Germany November 9, 1937 14 Claims.

one totalizer row comprising a number of special totalizers, and a multiple-item totalizer, in which row, in taking the total from the multiple-item totalizer, the multiple-item total is transferred, during one and the same machine operation, from the multiple-item totalizer to one of the special totalizers; for instance, a transaction totalizer, located in the same row.

To this end, in the device according to said patent, the shifting drum, for the totalizer row comprising the multiple-item totalizer and a number of special totalizers, is connected over a differential gearing to the differential device of the special key bank associated withsaid totalizer row, and to the mode of operation lever which, only if moved into multiple-item total position, causes the shifting drum to be rotated. Due to the said lever being automatically restored during the multiple-item total taking machine operation, said rotation of the drum is reversed. The cam groove of the shifting drum is so shaped that when the mode of operation'lever is moved into the multiple-item total position, the multipIe-item totalizer is always alined with the amount differential devices. As a consequence, with tliemode of operation lever set to multipleitem total position, the guide roller of the totalizer row is moved into a portion parallel to the amount differential planes, independently of the depressed special key, and then, upon restoring the mode of operation lever to add position, is moved into a screw-shaped portionof the cam groove of the shifting drum, according to the specialkey depressed each time.

Therefore, the object of the present invention is to enable the totalizer row including the multiple-item totalizer to move said shifting drum cam to select a special totalizer without necessitating the provision of a mode of operation lever. Another object is to provide means whereby, during the time theitems of a multiple-item transaction are entered'and during a portion'ofthe multiple-item totaltaking machine operation,

the shifting drum, for the row containing the multiple-item totalizer and the special totalizers, is disconnected from the differential device associated with'said row, and said drum is set exclusively bymeans of a special drive.

In the device according to the above-mentioned patent, the setting of the special differential device is always transferred to the shifting drum, whereas, according to the present invention, such transferring takes place only when the shifting drum is to be adjusted according to the setting of the special differentialdevice. Disconnecting the shifting drum and the special differential device may be effected, for instance, by a toggle joint in the gearing between the shifting drum and the special differential device, one shank of said toggle joint being adapted to be rigidly connected to the shifting drum or a part of its gearing While items of a multiple-item transaction are being entered and while the item total is being taken.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elem nts of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany'and form a part of this specification.

Keyboard The keyboard (Fig. 11) comprises amount keys Ill, one bank comprising article keys l2 each selecting a totalizer, one bank of insertable clerk keys l3, and a transaction key bank |4|8. Each of the keys 5, l6, 11, Received on account, Charge, and Paid out respectively, has allotted thereto a totalizer in the transaction totalizer row. No key is provided for Cash sales, but a Cash totalizer is provided within the transaction totalizer row, which is automatically selected by a fixed stop l9, as will be described hereinafter, each time a Cash sale is to be entered. To clear the Cash totalizer, the latter is selected upon depressing key l4.

To enter multiple-item transactions, one of the keys 2|, 22, 23 is depressed, under control of which a multiple-item totalizer in the transaction totalizer row is selected in order to accumulate on it the items of such transactions and to cause, upon clearing said totalizer, the print of the item total to be paid by the customer. Besides engaging the multiple-item totalizer, key 2| causes the issuance of an itemized check, whereas the keys 22, 23 control printing of slips inserted into the machine. Depressing key 22 for multipleitem entries causes slips to be imprinted upon, said slips having each item of a multiple-item transaction written thereon (however, in multiple-item total taking no slip is imprinted), and depressing key 23 causes a slip to be printed only in connection with multiple-item total taking.

The multiple-item keys 2|, 22, or 23, and the transaction keys M to l8, which are depressed for entering the first item of a multiple-item transaction, remain depressed until all the items of the transaction are entered and a total thereof is taken.

This bank is also provided with a lock 26 which, upon insertion of a certain key and turning said key to the left, conditions the machine for Reading or Sub-total (X) operations involving a transaction totalizer, whereas insertion of another key and turning said key to the right conditions the machine for Resetting or Total taking (Z) operations of said transaction totalizers. Neither of these keys need be inserted for a multiple-item total taking operation.

The machine is released for operation upon depressing a release or motor key 28.

Amount dzfierentz'als Associated with each amount bank of keys I is a differential mechanism similar to that shown in the above-mentioned Patent No. 2,101,636 and such mechanism will be but briefly described herein.

An actuator 3| (Fig. '7) is mounted on a shaft 3|] and is connected to a main difierential member 32 and a setting member 34 by a coupling pawl 33. The setting member 34 is connected by a beam 35 and a link 36 to mechanism, not shown herein, to set indicating and printing means.

The diiferential member 32 associated with each amount bank of keys drives a gear 6|, supported by a shaft 80, which gear meshes with a gear 62 with which selected totalizer wheels 63 are engaged. These totalizer wheels are denominationally interspersed on a shaft 34.

All amount actuators 3| are secured to a sleeve 4| on the shaft 35. The actuator on each end of said sleeve 4| has an arm 42 connected to a link 43 also connected to an arm 44 supported by a rod 45 and guided on blocks 45 rockable on a shaft 48. The rod 45 is supported by two levers 41 pivoted on a shaft 50. The levers 41 carry rollers 5| and 53 cooperating with cams 52 and 54 respectively, secured to a drive shaft 55 which receives one clockwise rotation during each machine operation.

During each machine operation, the cams 52 and 54 rotate the levers 47 first counter-clockwise about the shaft 55 and then back to normal. The counter-clockwise movement of the levers 41 carries the rod 45 towards the shaft 30, which rocks the arms 44 and blocks 4'0 clockwise about the shaft 48, whereupon the links 43 rock the arms 42, sleeve 4|, and actuators 3| clockwise until the differential member 32 is stopped by striking the stem of the depressed key I0. At this time, due to the continued movement of the actuator, a pin 38 of the coupling pawl is moved outwardly in a slot of the member 32, thus disengaging said member 32, the pawl 33, and setting member 34 from the actuator 3|. A nose on the pawl 33 now engages a notch in a stationary plate 9, and the actuator 3|, by passing the nose of the pawl 33, looks the pawl 33 and members 32 and 34 in their set positions.

Now a cam 49, pivoted on rod 45, contacts and moves the beam 35 to operate the link 36 to set the indicators and printers, not shown, according to the value of the key depressed.

Upon return of the levers 4'! to normal position, the rod 45 and arms 44 are returned and the links 43 restore the actuators 3| to their normal positions, whereupon said actuators strike pins 39 in the setting members 34, thus returning the differential members 32, the pawls 33, and the members 34 to their normal positions.

During this return movement of the differential members 32, the gears BI and 62, having been set differentially according to the value of the depressed keys, are returned home and the gears 62 add (see time chart Fig. 16), upon the now engaged totalizer wheels 53, the amounts commensurate with the values of said depressed keys. The means for engaging the totalizer wheels 33 with the gears 62 will be described later.

When there is no amount key depressed in a bank, a zero stop pawl 8 of that bank, by means of a pin 1 thereon, retains the differential member 32 and associated differential parts in their normal positions. Depression of an amount key l0 operates a slide |38, whereupon a pin 6 on slide I38 rocks the pawl 8 and moves the pin 1 out of the path of the differential member 32.

Transaction difierential The transaction key bank has associated with it a differential device (Fig. 1) substantially like the amount differential above described except that the difierential member has no gear teeth.

Parts similar to those of the amount differential are given the same reference numbers, increased by 200. This transaction differential includes an actuator 23! mounted on the shaft 30, a main differential member 232, a coupling pawl 233, and a setting member 234. The setting member 234 is connected by a curved lever or beam 235 and a link 236 to a gear segment 231 which adjusts the appropriate indicating means and type wheels (not shown).

The transaction actuator 23l is secured to a sleeve 24f rotatable about the shaft 30. The actuator 23l has an arm 242 connected to a driving link 243 whereby said actuatoris first rocked in clockwise direction by 90 degrees, and then restored to normal.

The transaction link 243 (Fig. 1) is connected to an arm 244 supported by a rod 245 in axial alignmentwith the rod 45 associated with the amount differentials. The arm 244 is guided by a block 246 rockable on the shaft 43. 245 is supported by two levers 24! (Figs. 1 and 2) pivoted on the shaft 50. The levers 241 carry rollers 25l and 253 which cooperate with cams 252 and 254 respectively secured to the drive shaft 55, which, as previously stated, receives one clockwise rotation during each machine operation. The cams-are so timed as to become operative prior to operation of the cams52 and 54 (see Fig. 16).

Therefore, during each machine operation the cams 252 and 254 rotate thelevers 241 first counter-clockwise about the shaft 50 and then back to normal. The counter-clockwise movement of the levers-241 carries the rod 245 towards the shaft 30, which rocks the arm 244 and block 246 clockwise about the shaft 48, whereupon the link 243 rocks the arm 242, sleeve 24], and actuator 23l clockwise. Upon return of' the levers 241 to normal, the rod 245 and arm 244 are returned and the link 243 restores the actuator 23f to normal position.

Upon operating the above differential mechanism after depressing a key of the transaction key bank, the main differential member 232, coupling pawl 233, and setting member 234 are carried. along while the actuator 23I is rotated clockwise, until the main differential member 232 is stopped by the foot of the depressed key. Due to the fact that the actuator 23! continues moving and the main differential member. 232 is stopped, a pin .238 of. the coupling pawl 233 is guided outwardly in an inclined'slot of the main differential member 232, wherebythe differential member 232, coupling pawl .233, and setting member 234 are disconnected from the actuator 23L -At this time, a pointed extension-of the coupling pawl" 233 enters a corresponding. notch of a locking plate 9 fast on the key frame, and the actuator 23| moves underneath afoot of 'the coupling pawl 233, thereby holding the latter, the main differential member .232, and the setting member; 234 connected to it in the position set.

Now the curved: lever; or beam 235 linked to the setting member 234 is urged towards-the periphery of a hub by a cam -249. Thus the link 236 sets the gear segment 23! and its connected indicator according-to the key depressed.

The, actuator 23!, on; its return movement, strikes a pin 239 of the: setting member 234 and restores the differential member 232, the-pawl 233, and the setting-member 234. to; home positions while gearsegment 23'! remains in the position set until the next machine operation.

The rod If no key l4 to I8 (Figs. 1 and 10) is depressed,

the main differential member 232 is free to rotate in clockwise direction until it is stopped by a. fixed stop l9. Such adjustment of the main differential member 232 occurs when entering Cash transactions.

, By turning the lock 26 (Figs. 11 and 13) the machine is conditioned for total or sub-total taking operations from the transaction totalizers, and by means of a link 263 (Figs. 1 and 13) having a pin 12 engaging a slot of an arm 14 pivoted on a solid screw 13, rotates said arm 14 counterclockwise and by means of spring 15, moves a stop pawl 16 into the path of extension 11. Thereafter, upon operation of the machine, the stop 16 arrests the main'differential member 232 in zero position, provided no key l4 to I8 is depressed in the transaction key bank. If, however, after the machine is conditioned for total or sub-total taking, one of the keys 14 to I! is depressed, the stop pawl 16 is restored to ineffective position against the action of spring 15, by means of key detents 206 or 290 (Fig. 13), which are moved upwardly upon depressing one of said keys, so that the main differential member 232 can be adjusted by the foot of the depressed key M to I! or by the stop Hi. In order to restore the zero stop pawl 16, the detents 20B and 290 are provided with shoulders 206a and 293a, respectively, which coact with a flange i258 on the zero stop pawl 16, when either detent is moved upwardly by the depression of a key I4 to H, to restore the zero stop pawl to its normal position.

The link 263 (Fig. 13) is moved to operate the stop 16 by a gear 269 on the lock barrel 26 meshing with teeth 268 of a slide 261 which has a pin 266 engaging a cam slot 265 of a lever 2B4 pivoted to the bar 253.

Totalieers While the machine shown in the above-mentioned pending application Serial No. 238,546 has four rows of interspersed totalizers, only a part of one row is shown in the present case (Figs. 7 and 9).

The totalizer wheels 63 are denominationally mounted on the shaft64 supported by two arms 65 (only one being shown) which are secured to a rock-shaft 66. The shaft 66 is adapted to be axially shifted, by means later described to bring the wheels 63 of the selected totalizer opposite the differential gears 62 with which the wheels 63 are engaged to have amounts added thereto and to be cleared thereby.

Totalieer selection The selection of the transaction totalizers is effected by the transaction differential mechanism described above. Thus, depression of a transaction key l5 to IT, when entering single-item transactions, controls the differential to select the corresponding transaction totalizer. When no key l5 to I8 is depressed, the transaction differential is arrested by the stop H), which selects the Cash totalizer. During total-taking operations, the Cash totalizer is selected by key M.

The selection of the multiple-item totalizer for receiving multiple items is effected by the same transaction differential, when a multiple-item 2| to 23 is depressed. In entering the items of a multiple-item transaction, it is necessary to depress an amount key, a transaction key (except for cash transactions), and a multiple-item key 2I to 23. At the end of each multiple item entry operation, only the amount keys are released. When taking a total of a multiple-item transaction, no amount key is depressed, and the simple depression of the motor bar 28 causes the total to be taken from the multiple-item totalizer and to be transferred to the transaction totalizer corresponding to the transaction key which is depressed.

For taking a total of a transaction totaliz er, it is necessary first to condition the machine for total-taking by turning lock 26.

The gear segment 231 (Fig. 1), set by the transaction differential device allotted to the transaction keys I4 to I8, is connected by a link 86 (Figs. 1 and 2) to one end of a curved lever or beam '40 (Fig. 2), the other end of which is linked to a setting'segment 81. The outward edge of the lever or beam 40 is engaged by a guide roller IOI of slide I02 guidedat either end on the shaft 30 and pin I03 of a cam disk I04 fast on the shaft 48. Another guide roller I08 of a slide I02 engages the cam'di'sk I04. Normally, the shaft 48, which, in a manner described hereinafter, can be rotated under control of the multiple-item keys 2I to 23, is positioned as shown in Fig. 2, in which the cam disk I04 acts upon the guide roller I08 of slide I92, so that its other roller IOI keeps the lever or beam 40 in contact with the periphery of a hub. With the cam disk I04 positioned so, the setting segment 81 is adjusted by the setting member 234. The setting segment 81 (Figs. 2 and 9) is in mesh with a gear wheel 88 rotatable on a shaft 80, said gear wheel being rigidly connected to a wheel 89 of greater diameter also mounted on shaft 80. Wheel 89 meshes with wheel 90 rigidly connected to a cam groove roller 95 rotatably but unshiftably mounted on a stationary stud 34. With the cam disk I04 positioned as shown in Fig. 2, cam groove roller 95 is.positioned according to the depressed transaction key I4. to I8 upon setting the transaction differential device.

Secured to the right-hand end of the shaft 48 is a lever I01 (Figs. 3, 4, and 18) [connected by a link I08 to lever I09 pivoted on the stationary stud H0. About midways, lever I09 hasattached thereto a coupling lever Ii I which, by a link H2, is connected to a two-armed lever H3. .The latter is pivoted on stud II4 of a two-armed lever H5 pivoted on the stud H0, the lever II5 being connected by a link H6 to an arm II1 pinned to a shaft 32. The slotted upper end ofthe twoarmed lever II3 embracespin IIB of an intermediate lever II9 pivoted on the stud III] and having a slot to embrace a pin of a key detent I20. The latter is shiftably attached to the control key bank and has bevelled surfaces so arranged that, upon depressing a multiple-item key 2I to 23, said detent is moved upwards.

Moreover, the intermediate lever H9 is connected by a link I2I to an arm I22 rotatably mounted on a shaft 60. A pin I23 of the arm I22 carries a two-armed lever I24, the forked upper end of said lever embracing a pin I25 of an arm I28 fast on the shaft 60.

The shaft 60 carries a tube having secured thereto two arms 33I (only one of which is shown in Fig. 10), which arms 33I support a rod 332. The rod 332 carries a two-armed lever 333, the lower arm being connected by a link 334 to an arm 335 which, upon depression of the motor bar 28 (Fig. 12), is moved clockwise by the fo1- lowing means.

The motor bar 28, through a slide 30I and its attached to arm II1 fast on shaft 92.

pin 303, rocks a bell-crank 304 counter-clockwise, which, by means of a link 308, rocks an arm 301 and a bail 308 to which it is connected, ina clockwise direction. The bail 308 is connected to the sleeve 309, and therefore, causes the abovementioned clockwise movement (Fig. 10) of the arm 335. When the operator releases the depressed motor bar 28, a spring 3I3 (Fig. 12) returns the above-mentioned train of mechanism, from the key 28 to the arm 335, to their normal positions.

The rod 332 carries means associated with all of the amount banks of keys I0, but, in the present application, the means associated with one bank only will be described.

A slide 331 pivoted to a detent or bar 338 is guided by the rod 332. This bar 338 is moved to the right (Fig. 10) upon depression of any amount key in the associated key bank, whereupon the left end or wall of the slot in the slide 331 contacts the rod 332.

The upper arm of the lever 333 surrounds a pin 329 of an arm 336 fast to the shaft 60.

If no amount key is depressed, then upon depression of the motor bar 28 (Fig. 12) the lever 335 is rocked clockwise (Fig. 10) 'and the lever 333 is rocked about the pin 329 as the rod 33! moves to the left in the slot of the slide 331, and therefore the shaft is not rocked. 7

However, when an amount key I8 is depressed, the slide 331 is moved to the right (Fig. 10) until the left wall of its slot contacts the rod 332, thus causing the lever 333 to pivot on said rod upon operation of the motor bar 28. Therefore the pin 329 now rocks the arm 33S and shaft 88 clockwise. In all other machine operations except No sale, the shaft 89 occupies the position shown in Figs. 4 and 10.

As stated above, the arm 335 and associated parts return to home position immediately upon release of the motor bar 28; however, the shaft 69 is maintained in its rocked position by means to be described, until the machine operation is completed.

For a No sale operation, the shaft 80 must be rocked by depression of the motor bar 28 and therefore the rod 332 must be held upon depression of the No sale key I8. This is accomplished by a hook 393 (Fig. 1) in the following manner.

A bail 394, one arm of which rides on the shaft 92 and the other arm of which is secured to a tube 395, has a slot through which the hook 393 passes so as to be operated thereby. A bail 398 is also secured to the tube 395 and is connected by a link 391 to a key-operated slide 398 of the transaction key bank. This slide 398 has camming projections cooperating with the Received on account key I5, the Paid out key I1, and the "No sale key I8. The camming projections cooperating with the keys I5 and I1 are so shaped that depression of either of said keys, through upon operation of the motor bar 28. Therefore} the shaft 60 is rocked clockwise upon operation of the motor bar 28, after depression of the No sale key I8.

The lower arm of lever I24 (Figs. 4, 5, and 17) is connected by a link I21 to a link I28 which is shaped recess I3I of this link I28 is engaged by a pin I29 of a slide I30,'which is guided on the shaft 55 and about a stationary stud, and has a guideroller I32 to engage the cam groove of a disk 56 fast on shaft 55. Disk 56 has teeth 51 constantly meshing with a gear 58 of the same diameter. The gear 58'is fast on the main drive shaft 50 and rigidly connected to a cam groove disk 59 (Fig; having teeth -meshing'with a gear I 4| of half the diameter, which is rotatably mounted on the stationary sleeve I42 and is rotated twice in clockwise direction (Fig. 4) by means ofthe hand crank I43 when the machine is manually operated. This actuating movement is transferred to the shafts and as a single revolution. The cam groove of the cam disk 59 is engaged by a roller I45 of a slide I48 guided on shaft 50 and sleeve'I42 and having a'pin I41 normally extending into a recess I33 in the coupling lever III.

If no amount key and no multiple-item key are depressed, the parts of the mechanism described are positioned as shown in Fig, 4. If, now, the machine is released for sub-total taking or clearing one of the transaction totalizers, the two slides I30 and I46 move idly, as their pins I29 and I41 move idly to and fro within the recesses I3I and I33 of the coupling rod I28 andlever III respectively.

If the amount of a single item transaction is set up on the amount keys I0, shaft 60, upon depression of the motor key 28, is rotated clockwise. At this time, arm I26, being fast on shaft 60, rocks the lever I24 about stud I23, as arm I22 remains stationary due to the fact that no multiple-item key is depressed for single-item transactionentries. Through link I21, the rotation of the lever I24 is transferred to the coupling rod I28, which thereby is moved to the right until a projection I34 thereof is moved above the pin I29 of the slide I30. As the coupling lever III is not displaced, the slide I48 moves idly. Slide I30, however, moving upwardlyfcarries along the coupling rod I28 after one-third of the machine operation and restores it to normal near the end of the machine operation. Due to this, shaft 92 is rotated counter-clockwise and is returned again. Through the link I I6, this movement is transferred to the lever I I5 having the stud II4, rocking the lever II3 about'the held pin H8, whereby, through the link II2,'the coupling lever III is pulled to the left. This displacement, however, exerts no practical effects; as pin I41 of slide I46 does not come into contact with the coupling lever I II even in this new position.

If, for the purpose of registering an item of a multiple-item transaction, a multiple-itemkey, as well as an amount key, is depressed, the parts are displaced through the shaft in accordance with the depressed amount keys and the depressed multiple-item key.

Upon depression of a multiple-item key, the lever H3 is rocked, by the key detent I20 and the angular lever I I9, in counter-clockwise direction about stud II4, whereby the coupling lever III is moved to the right until a step I35 of its recess I33 is moved underneath the pin I41 of slide- I48. Due to the depression of an amount key, the projection I34 of the coupling rod I28 has been moved over the pin I29 of the slide I30 by the shaft 60. The movement of the key detent I20 also, through lever H9 and link I2I, causes the arm I22 to rock in counter-clockwise direction. At this time, the stud I23 'ofthe' arm I22'rocks the lever I24 in counter-clockwise direction about pin I25 and, through'the link I21, moves the coupling rod I28 another step to the right, so that the left shank of the U- shaped recess I3I is moved into the path of pin I29. Thus, in such machine operations; that is,

in entering items of multiple-itemtransactions, the slide I30 moves idly and the shaft 92 will not'be rotated.

Shortly after'the beginning of the machine operation, the slide I46 is moved down'by the cam disk 59,the pin I41 carrying along the coupling lever III, and, by means of'thelever I09, link I08, and lever I01, rotates the shaft 48 in clockwise direction'against the action of a spring I48. By this clockwise rotation of the shaft 48, the cam of the disk I04 (Fig. 2) fast on shaft 48 is removed from the roller I06. At the same time, the pin I03 of disk I04 pulls the slide I 02 upwards. A'pin'99 of slide I02, extending into an arcuate recess" 98 of the setting segment 81, strikes at this time the right-hand end'of said recess 98"and moves the setting segment 81 out of the position into which it Was brought in the previous machine operation, and moves it in counter-clockwise direction into the first or No sale key position.

Due to this, the device about to be described moves the totalizer row comprising the multipleitem and'the transaction totalizers into the position corresponding to key I8, in which position the adding wheels of the multiple-item totalizer are aligned with the amount differential mem bers. From this it results that with a multipleitem key and an amount key, depressedthe multiple-item totalizer is automatically selected;

This selection is effected at the beginning of the first multiple-item machine operation and is maintained while the items of a multiple-item transaction are entered, as at this time, due to the clockwise movement of the lever I01 by the slide I46, the spring I48 stands past a dead center line drawn from the center of shaft 48 through the center of the stud to which the spring I48 is attached. During the entering of subsequent items of the respective multiple-item transaction, the movement of the slide I4ii does not affect the shaft 48, so that the amounts of the items of a multiple-item transaction are entered into the multiple-item totalizer.

Also in taking the multiple-item total, the multiple-item totalizer, during thefirst third of the machine operation-that is, for the purposes of resetting-is maintained selected due to the described setting of shaft 48. In multiple-item total taking operations, no amount key is depressed, and therefore the previously depressed multiple-item key maintains the coupling link I28 in its intermediate position where cam 56, through pitman I30, can lower link I28 and therefore rock shaft 92. Therefore, after the first third of this machine operation, shaft 92 is rotated counter-clockwise in the manner described, and due to this, by means of the link II6, lever II5, pin II4, lever II3, and link II2, the coupling lever III is pulled to the left, whereby its edge I36 is moved above pin I41 which at this time is in its lower position. Now, when the cam groove disk 59 moves slide I46 up again, the shaft 48 is restored to home position against the action of the spring I48, which is now moved back past the 'dead center into its normal position. In home position, shaft 48 is held again by spring I48; While shaft 48 'is returned, its cam disk I04 (Fig. 2) moves the slide I02 down again, the

roller I6I of said slide moving the leveror beam 49 again into contact with the hub. As the appropriate setting segment 231, which was set by a minimum movement device 235-236 according to the depressed key I to I1, or the stop I9, depending upon the transaction to be recorded, is held in this position, thesetting segment 61, by the roller 'i9I bearing upon the lever or beam' 46, is rocked in clockwise direction a corresponding distance. At this time the transaction totalize'r'row is gagement with the same to accumulate the total taken from the multiple-item totalizer.

Secured to the shaft 56 is a pair of cams 225 and 226 cooperating with rollers 223 and 224 carried by a lever 222 pivoted on a stud I99. A link 22! connects the disk 239 with the lever 222.

When the pin I83 is moved into cooperative relationship with the disk 23!), by means later described, the disk 236 is rocked clockwise by the cams 225 and 226, the lever 222, and the link 22I, whereupon, through the pin I93 and arms HI and I66, the segment I66 is rocked counter-clockwise. Therefore, the shaft I63 and stud I62 rock the lever I6I, shaft 66, and arm 65 counter-clock- To aline the cam'groove roll 95 after adjustment, and to hold it in the'position set, the toothed wheel 89 has locking teeth I50 for a beam I5I to engage therein, said beam being carried by two arms I52 mounted on shaft I53. Durunder the tension of a minor spring (not shown), engages the locking teeth I56 so that it may yield. After the wheel 89 isfinally adjusted, beam I5I is locked within the'respective notch by r ing the setting of wheel 89, said locking beam,

means of cam disk I54 fast onthe main drive shaft 59 and shaped suitably, andthus the cam groove ro1l.95 is held in the position set while the totalizers are operated.

Roll 95 (Figs. 2, 6, and 9), has a cam groove engaged by a guide roller 96. on. a shift fork 91 which is rotatably but unshiftably mounted on the transaction totalizer rock shaft 66. This fork is securedagainst rotation by its arms engaging, from either side, the periphery of the appropriate cam'roll 95. Upon rotation of the cam roll 95, the totalizer rock shaft 66 is shifted and can be rocked out by means of an adding wheel engaging and disengaging device to be later described.

The cam groove of roll 95 (shown diagrammatically in Fig. 6) is so shaped that, if the transaction differential device is adjusted by the transaction key I8 (No sale) or the stop pawl 16, the adding wheels of the multiple-item totalizer are alined with the amount differentials. The totalizer row is so positioned also by the segment 61 when restored by the slide I62.

Totalizer engaging means The totalizer engaging means will be briefly described. Secured to the shaft 66 (Figs. 8 and shaft I63 has teeth meshing with a, gear segment I66 pivoted on a stud I66 supported in axial alinement with the shaft 66 by the frame 2. An integral arm I69 of the segment I64 is normally held against a stud I 51 by a spring I65. The segment I66 has a hub to which is secured an arm I 68, and the latter and the arm I66 carry a shaft 569. Secured to a hub on the shaft I69 are arms HI and IE2. A link I13-connects the arm I12 to a locking segment I14 pivoted on the shaft 86, and a link I15 connects the segment I16 to a lever I16 pivoted on a sleeve 29 which supports the shaft 36. A spring E11 normally holds the lever I16 against a stud I18, thus holding the arms HI and I22 in the position shown in Fig. 8.

The arm HI carries pins I8I and I83 (Figs. 8 and 9) cooperating with adding and resetting coupling disks 2H) and 236 respectively, and the arm H2 has a pin I82 cooperating'with a reading disk 226.

The latter is fast' wise, thus engaging the totalizer wheels 63 with the actuating gears 62.

The cams 225 and 226 cause such engagement of the wheels 63 with the gears 62 on total taking time; that is, before the differential members 32 (Fig. 7) are moved clockwise, thus causing the engaged totalizer to be reset.

There is a pair of cams I235 and I236 (Fig. 14) substantially like the cams 225 and 226 for operating the adding disk 2E6 to engage the totalizer wheels 63 with the gears 62 on adding time when the pin IBI is moved into engagement with the disk 2I 0.

Another similar pair of cams 2235 and 2236 operates the reading disk 229 to engage the wheels 63 with the gears 62 on reading or subtotal time when the pin I62 is engaged with said disk 220.

A link I19 (Fig. 13) connects the lever I16 with a bar I85 which is connected to a lever I86 pivoted on a stud I81. A roller I86 on the lever I86 contacts a cam I89 driven by the shaft 55. A pin I9I connects the lever I86 with a lever I92 pivoted on the stud I81. This lever I92 has a roller I93 contacting a cam I96 drivenby the shaft 55.

Connecting the bar I85 to a lever 342 pivoted on the shaft 66 is a link 34L The lever 662 normally contacts a rod 343 and the upper end of said lever is outside the path of a lever 344 secured to the shaft 69. This shaft 66, when rotated, moves lever 364 into the path of the lever 342 and therefore, when the cams I69 and I 94 draw the bar I65 towards the right, the lever 342, being held by the lever 364, causes the bar I85, by means of the link I19, lever I16, link I15, and segment I14, to rock the arms HI and I12, as above described, to effect engagement of the pin I8I with its associated disk 2 I6.

During total taking shoulder 213 of a disk 353 on a shaft 266 cooperates with a pin 262 on the lever 392 to effect proper engagement of the pin I83 with the resetting disk 239.

The link 263 (Fig. 13) connects a disk 26I with a lever 264, and so the disk 26! is operated by the lock barrel 26 when the same is actuated to set the machine for a read or reset operation. When so operated, a stop surface 21I of the disk 26I is moved out of the path of the pin 262.

The disk 26I is connected by a bail and a rod 29I (Fig. 20) to a disk 282. A link 284 (Fig. 19) is pivoted to the rod 26I and to a-link 295 connected to an arm 255 secured to an arm 256 carrying a pin 256 cooperating with the transaction detents 266 and 269. The arms 255 and 256 are pivoted on a shaft 259 and, upon depression of a key I4 to I1, said arms are rocked counterclockwise, whereupon a pin 285 is moved freely in the horizontal part of a slot in a lever 281 pivoted on a rod 296. The lever 281 is normally held in the position shown by a spring 29! connected to a lever 289, which lever is connected to the lever 281 by a link I288. The lever 261 has an extension at its lower end bearing against a hub on shaft 260 to determine its normal position.

If the lock 26 is set to Read or Reset, the disk 26I is rotated one or two steps by means above described, whereupon the link 284 rocks the link 285' to set the pin 286 into either its middle or its top position in the vertical part of the slot in the lever 231. 'Now, if a transaction key is depressed, the lever 28! is rocked counterclockwise one or two steps, depending upon the position of the pin286 in the slot of the lever 281, and, through a pin 288, the disk 259 is rocked to position its surface? or-2I3 opposite the pin 262 of the lever 342.

Therefore, when the bar I85 is pulled down, the lever 342 follows until the pin 262 contacts either the surface 212 or 213, and the remainder of the motion of bar I85 then rocks the arms Ill and H2 two or one steps. When rocked two steps, the pin I82 engages the disk 220 for a reading operation.

To take a multiple-item total, the lock 26 is not operated and consequently the disk 259 remains in normal position (Fig. 13). Moreover, since there is no amount key I!) pressed at such time, the shaft 60 and lever 344 will not be rotated and the lever 342 is not locked. Therefore the full motion of the bar I85 is taken up by the lever 342 until the pin 252 contacts the surface 2H of the disk 26L This is about one-third of the motion of the lever 342, and so the remaining twothirds of the motion of the bar I85 is transmitted to the arms III and H2, whereby the pin I62 is engaged with the Read or Sub-total disk 220, thus causing engagement of the wheels 63 of the multiple-item totalizer, with the gears 62 prior to the movement of the differential members 32 and disengagement therefrom after such movement is finished. The cam disks 2235 and 2235 (Fig. 15) are so shaped that, after the amount has been taken from the totalizer, the totalizer is temporarily disengaged from the differential members, until the totalizer group has been shifted to bring the transaction totalizer in line with the amount differential members, whereupon the cams again engage the transaction totalizer with the amount differential members. The engagement of the transaction totalizer with the differential members is effected by cams 2235 and 2236 prior to the return movement of said differential members and disengaged again after amount entering is completed.

Such reading operation is necessary for taking a multiple-item total, since the multiple-item totalizer must be reset and the total taken therefrom must be transferred to a selected transaction totalizer in the same row.
